DSCR Loans on 5+ Unit Multifamily and Mixed-Use Properties

The four-unit line is the most consequential threshold in investor lending, and most borrowers don't discover why until they're mid-application on a five-unit deal. Everything below five units is residential: the appraisal is a 1004 or 1025, the income figure comes off a 1007 rent schedule, and the DSCR calculation is gross market rent divided by PITIA. At five units the property becomes commercial collateral. The appraisal switches to a narrative or commercial form, the income figure becomes net operating income, and the DSCR calculation starts subtracting real operating expenses before it ever gets to debt service. Same borrower, same credit, same market — materially different loan.

The good news is that a real 5-10 unit DSCR market exists and has matured considerably. A decade ago an investor buying a six-unit had two options: a local bank with a 5-year balloon and a personal guaranty, or agency small-balance multifamily with a $1 million floor and a 60-day process. Today a meaningful slice of non-QM lenders will write a 30-year fixed DSCR loan on a 5-10 unit building with no tax returns and no DTI calculation, which is a genuinely different financing posture for a mid-size portfolio.

Where the DSCR math actually changes

On a 1-4 unit file, gross rent goes straight into the numerator. On a 5+ unit file, the underwriter builds NOI: gross scheduled rent, minus a vacancy factor, minus operating expenses. Vacancy is usually underwritten at 5% even if the building is fully occupied, and expense loads get imposed by the lender rather than accepted from the seller's P&L. Expect an expense ratio floor somewhere between 30% and 40% of effective gross income depending on the market and whether utilities are master-metered.

That floor is where deals die. A six-unit grossing $6,600/month looks like it clears easily against a $4,900 payment — a 1.35 ratio on gross rent. Run it properly: $6,600 gross, less 5% vacancy is $6,270 effective, less a 35% expense load is $4,076 NOI, against $4,900 debt service. That's a 0.83 DSCR, and the file is dead at most shops or repriced hard at the few that will go sub-1.0. Investors who cut their teeth on duplexes and triplexes are used to a friendlier formula, and the transition is worth modeling before you're under contract — the mechanics of how DSCR is calculated shift enough between the two categories that a mental model built on 2-4 unit DSCR loans will overstate your capacity by 30% or more.

Typical terms in the 5-10 unit space

Pricing sits roughly 50-125 bps above comparable 1-4 unit DSCR paper. Where a strong SFR file quotes 7.0-8.5% in the current market, a comparable 5-8 unit file lands closer to 7.75-9.5%. LTV caps tighten too: 70-75% on purchase is standard, with a handful of lenders reaching 75% for DSCR above 1.25 and clean rent rolls, and 65-70% typical on cash-out. Minimum loan amounts usually start at $150,000-$250,000, which quietly eliminates a lot of low-basis Midwest small multifamily from the program.

Structure is where 5+ unit DSCR paper is most attractive relative to bank debt. Thirty-year fixed and 30-year fixed with a 10-year interest-only period are both available, versus the 5/25 or 7/23 balloon structures most community banks offer. Prepayment penalties run harder than on residential DSCR — 5-4-3-2-1 step-downs are common where 3-2-1 dominates the SFR side, and yield maintenance shows up occasionally on larger balances. Reserve requirements typically run 6-9 months of PITIA versus 3-6 on residential files.

Mixed-use: the residential percentage test

Mixed-use — ground-floor retail with apartments above, the classic Main Street asset — is underwritten by residential percentage. Most DSCR lenders that touch mixed-use require the residential square footage to be at least 51% of total, and a large share want 60-75%. Below the threshold the property is straight commercial and falls outside almost every DSCR program.

Commercial tenant quality then drives pricing. A ground-floor space leased to a regional credit tenant on a five-year triple-net lease is underwritten near face value. A month-to-month lease to an uninsured single-location business, or a vacant storefront, usually gets the commercial income haircut 25-50% or excluded entirely. Vacant commercial space is the single most common reason a mixed-use DSCR file gets declined — the lender underwrites the residential NOI alone and the ratio doesn't clear. Legacy Main Street stock in markets like Cleveland and Pittsburgh is heavily mixed-use, and the ones that finance cleanly are the ones with the storefront already leased at signing.

Documentation you'll need that residential files don't require

The file is heavier. Beyond the standard DSCR package, expect a certified rent roll signed by the borrower, 12-24 months of trailing operating statements, copies of every executed lease, and a schedule of any tenant deposits held. Many lenders order a property condition report — a commercial-grade inspection running $1,500-$3,500 depending on size — and a Phase I environmental screen if there's a commercial component with any historical dry cleaner, auto, or fuel use. That last one is not a formality: a Phase I flag on a former gas station or dry cleaner parcel will stop a mixed-use file cold.

Closing costs run higher accordingly. Where a residential DSCR closing lands in the 2-4% range, budget 3-5.5% on a 5-10 unit or mixed-use file once the commercial appraisal, PCR, environmental, and heavier legal review are stacked in.

Entity vesting is mandatory, not optional

On 1-4 unit DSCR files, LLC vesting is usually preferred but occasionally negotiable. On 5+ unit and mixed-use files it is effectively a hard requirement — every lender in the space will require title in an LLC or LP, an operating agreement, a certificate of good standing, and a completed entity questionnaire. Single-purpose entities are strongly preferred over a single LLC holding twenty doors, because the lender wants clean collateral isolation if things go sideways.

Non-recourse availability improves somewhat at this size class. On residential DSCR, non-recourse is common. On 5-10 unit paper, most lenders will still write non-recourse with standard bad-boy carve-outs, but a few pull back to a partial guaranty at higher LTVs. States with slow judicial foreclosure timelines see tighter terms, so it's worth checking state-level foreclosure and prepay rules alongside the pricing sheet.

When the 5+ unit DSCR loan is the right tool

The clearest use cases are the ones where agency small-balance doesn't fit and bank debt is unattractive. Loan sizes between $200,000 and $1 million sit below most agency floors and above what a community bank will do without a full financial workup. Borrowers with strong assets but messy or minimal tax returns get underwritten on the property rather than the return. And investors who specifically want 30-year fixed amortization on small multifamily — rather than refinancing a balloon every five years into whatever rate environment exists — are paying that 50-125 bp premium for exactly that certainty.

Where it's the wrong tool: heavy value-add plays with substantial vacancy at acquisition. A 5+ unit DSCR loan needs in-place income to clear the ratio, so a half-empty building doesn't qualify. That deal wants bridge or hard money first and a DSCR takeout after stabilization, which is the same sequencing logic behind the refinance waterfall approach. Run the stabilized numbers first — the DSCR ratio and cash flow calculators will tell you quickly whether the post-rehab NOI supports a takeout at 70-75% LTV — and then compare quotes across lenders that actually write 5+ unit and mixed-use DSCR paper, because the subset is meaningfully smaller than the residential DSCR field and the pricing spread between them is wider.
